Scope
Remove and replace damaged stormwater pipes
Rebuild the eroded stream pathway
Stabilize banks and prevent further erosion
After a severe thunderstorm in late July caused heavy erosion and redirected the stream bed, RemacUSA, Inc. was called in to restore the natural flow, replace damaged infrastructure, and protect neighboring properties from future flood risks.
Services Performed
✅ Stormwater Remediation & Stream Realignment
Excavated and regraded the eroded stream bed to reestablish a stable flow path
Reconstructed and compacted stream banks using clean fill and natural contours to resist future washouts
✅ Pipe Removal & Replacement
Safely removed collapsed or undersized storm pipes contributing to flow restrictions
Installed larger, corrosion-resistant HDPE piping to handle future high-volume runoff events
✅ Erosion & Sediment Control (ESC)
Installed silt fencing and check dams prior to ground disturbance
Deployed riprap and turf reinforcement matting post-restoration to stabilize stream edges
✅ Site Access & Neighborhood Coordination
Created temporary access paths for machinery with minimal impact to residential properties
Provided daily briefings and updates to homeowners’ association during execution
Challenges & Solutions
Challenge
The July 2025 thunderstorm caused excessive water velocity that deeply scoured the stream banks, displaced boulders, and widened the channel by several feet, damaging nearby lawns and undermining footpath access.
Solution
RemacUSA used topographic assessment tools and pre-storm maps to realign the stream to its original path. Erosion-resistant fill was compacted in layers to rebuild the banks, and geotextile fabric was used below the riprap to prevent future undermining.
Materials Recycled
♻️ Concrete & Debris
Old broken pipe sections were removed and sent to a certified concrete recycling facility in Montgomery County
♻️ Excavated Soil & Boulders
Clean soil was reused onsite for grading and slope support
Displaced native boulders were reintroduced into the stream to slow water flow and promote natural dispersion
